Thanks for the reply. I understand that reprojection would 'mix' pixels and can affect l2flags. But in reprojected files also l2flag array looks fine. It is the flag_percentages that are not correct in reprojected files. This is what I find in OLCI L2 files.  When I checked the same in ...

Hello,      I have been processing L1 to L2 using l2gen. One of the  output OLCI L2 files has the following flag statistics (I believe it in % of pixels with each flag value in the image):ATMFAIL      0.0000LAND      72.8164PRODWARN    ...

Thank you John.I used quotes but the manifest url still did not work. But when I tried 'requested_files' url from the manifest.txt file it worked! I was wondering if there are multiple tar 'requested_files' then that is what is required! In any case - at least first bunch of files ar...

Hello,    I am trying to download MODIS L1A data that I ordered using wget but I get the following -wget worked before so not sure what might be the problem. I'd appreciate your help. My data Order number is Data order [5080c0f01685fc5a].Thank you.Amita========wget "(link=)oceandata.sci.gsfc.na...

This is great! Will work on this.
Thanks so much again for your help.

Hi Sean,   So just to clarify:   Should I use gpt (geocrop?) to first extract domain in L1A and GEO files? Then generate L1B?   I am not sure if I use lonlat2linpix to get line-pix limits for L1A how would that be communicated to modis_L1B.py. And the GEO file will stil...

Hi Sean,     Yes, the goal is to track features in the Chesapeake Bay - that is why the 250 m resolution.     I first do the following       lonlat2pixline A2019297182500.L1B_LAC  A2019297182500.GEO  -r 1000 -x 1 -y 1 -77.01 36.7 -75.66 39....

Hi   Yes, I can subset the data -- am working on that.  I am working between my server and Mac  as on my Mac I can not generate GEO and L1B files and can not get L2 file on my server as l2gen has problem!    I am setting resolution=250 in my l2gen processing    1) ...

Hello,  I generated MODIS L1B files and GEO file on my server and generated L2 file on my Mac via GUI! I got the L2 file and I could visualize layers. However, when I closed the file and tried to open it  later  I get Java Memory error!An exception error occurred:Type: java.util.concu...

Thanks much Sean.
Perhaps I will request the system admin to run modis_GEO.py once so that de200.eos gets created! Then it  might work for subsequent processing I hope.
